Cutting Drywall

A necessary skill for patching holes in walls or putting up new pieces of
drywall is how to cut it. It is a very straight forward process and, if you
don't cut yourself with the utility knife, relatively painless.

Measure the opening you intend to cover with drywall.
Mark the sheet of drywall where you want to cut it. If
the distance is small, you can use a straight-edge, otherwise you will have to
mark the sheet on either side and snap a line using the chalk line.

Score through the paper on front face

Step 2:

Using the utility knife, cut the drywall along the
line. Note that it is not necessary to try to cut all the way through the
sheet. All you need to do is cut the paper.

Bend and break drywall

Step 3:

Putting one hand on either side of the cut and, with the cut still facing you,
snap the drywall away from you like you are closing a
book. This will snap the white material in the middle of the sheet.

From the backside, cut the paper

Step 4:

If the piece you are cutting is a small piece, it may be necessary to fold the
pieces perpendicular to each other and then cut the paper
on the other side with a utility knife. If the pieces are large you can
simply snap the pieces the other way and snap the paper on the other side.
